Abstract

The sorter, especially for waste excavated from old sites, has a separator to remove ferrous materials before the waste is fed into a rotary screen. The screen has a series of different sized grids that allow potentially useful waste materials to be separated by gravity. Its outlet end has separate collectors. The sorter, especially for waste excavated from old sites, has a separator to remove ferrous materials before the waste is fed into a rotary screen. The screen has a series of grids (2, 3, 4) of different sizes that allow potentially useful waste materials (6, 7, 8) to be separated by gravity. Its outlet end has separate collectors for bulky items (9) and plastics (10), with the latter recovered by a Venturi effect. The sorter also has a blower for lightweight materials, and an intermittent axial-flow turbine to deal with excess moisture.

Le dispositif, selon l'invention, permet non seulement la valorisation des déchets triés, l'identification et le stockage des déchets ultimes, mais de plus, la réhabilitation des anciennes zones de stockage en nouveàu centre d'enfouissement mis aux normes, conformément notamment de l'arrêté du 09 septembre 1997, relatif aux décharges existantes et aux nouvelles installations de déchets ménagers o et/ouassimilés. L'invention permet donc une poursuite d'exploitation des anciens site de stockage, voir leur réhabilitation, un prolongement de leur durée de vie, et de leur surveillance, une limitation d'ouvertures de nouveaux-sites, ainsi qu'une diminution notable des problèmes environnementaux, ainsi qu'une élimination d'une pollution latente ou existante due à la présence d'anciens sites de stockage de déchets non contrôlés. Selon les modes de réalisation, lensemble comporte: - une bande transporteuse acheminant les déchets vers un trommel - un système type overband, permettant la séparation des éléments ferreux des  The device according to the invention allows not only the recovery of sorted waste, the identification and storage of ultimate waste, but also the rehabilitation of old storage areas in new landfill center brought up to standards, in particular of the decree of September 9, 1997, relating to existing landfills and new installations of household o and / or similar waste. The invention therefore allows continued operation of old storage sites, see their rehabilitation, an extension of their lifespan, and their monitoring, a limitation of openings of new sites, as well as a significant reduction in environmental problems, as well as the elimination of latent or existing pollution due to the presence of old uncontrolled waste storage sites. According to the embodiments, the assembly comprises: - a conveyor belt conveying the waste towards a trommel - an overband type system, allowing the separation of the ferrous elements from the
